Proud papa and pseudo techo geek Brad Pitt celebrated the first birthday of his twin babies with Angelina Jolie with a quiet party at their home in Los Angeles. Vivienne and Knox Jolie-Pitt celebrated with their siblings, Maddox, 7, Pax, 5, Zahara, 4 and Shiloh, 3.

The elder kids helped bake two cakes for the youngest of the brood, one for each twin. In addition, Brad’s parents Jane and Bill Pitt flew in for the occasion, making the trek from Pitt’s hometown of Springfield, Missouri.
